Should I buy PayPal USD?

As a keen observer of the financial markets, I'm curious about the prospects of investing in PayPal USD. Given the company's dominance in the digital payments space and its expanding reach into other financial services, does PayPal offer a compelling investment opportunity? I understand the risks involved in any investment decision, but PayPal's growth trajectory and market position seem quite promising. Could you elaborate on the key factors I should consider before making a decision to buy PayPal USD? Specifically, what are the growth prospects for the company, how stable is its earnings potential, and what risks could potentially affect my investment?
